I can't install add-ons u-block origin. It said that the package is corrupted. It seems that the add-on is not properly signed in ff server

Most likely, the add-on is really not corrupt. The problem is, a critical certificate used in verifying add-on signatures expired. So everything fails testing.

A hotfix has been released for Firefox on Windows, Mac and Linux. More info in this article: Add-ons disabled or fail to install on Firefox.

There is not yet a fix for Android. The Add-ons team will post updates here: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/

If you want an unsupported temporary workaround, please see this thread: https://support.mozilla.org/questions/1258219

UPDATE: Firefox 66.0.4 should now be available on Google Play with the new certificate needed to solve this problem.
